Dynamic modifications of single player and multiplayer mode in a video game

ABSTRACT

A video game includes a single player mode where completion of storyline objectives advances the single player storyline. The video game also includes a multiplayer mode where a plurality of players can play on an instance of a multiplayer map. Storyline objectives from the single player mode are selected and made available for completion to players in the multiplayer mode, and the single player storylines can be advanced by players completing respective storyline objectives while playing in the multiplayer mode. Combinations of storyline objectives are selected from pending storyline objectives for players connecting to a multiplayer game for compatibility with multiplayer maps. Constraints can be used to determine compatibility.

DETAILED DESCRIPTION Introduction

Video games can have different gameplay modes to appeal to variousplayers, such as a single player mode and a multiplayer mode. Singleplayer mode allows a player to play alone, without interacting in thegame with any other player-controlled characters. Single player modesoften include a campaign featuring a storyline that takes place in avirtual world. Completing certain single player storyline objectives inthe single player mode can advance the storyline. The storylineobjectives may be sequenced. Some single player games can includenon-linear sequences of storyline objectives that branch in differentdirections based on the in-game choices of the player. Progress throughthe storyline can be tracked based on the completion of storylineobjectives while playing in the single player storyline mode. In somevideo games, progress through the storyline is additionally oralternatively tracked through the completion of different levels, acts,zones, chapters, or the like, each of which may include one or morestoryline objectives.

At certain parts of a storyline, an optional side quest can be madeavailable to a player in response to the player's interactions withinthe virtual world. The side quests may include optional storylineobjectives that, when completed, will cause certain events to occurwithin the single player mode but are not necessary to progress throughthe main storyline. For example, within the single player mode, anon-player character (NPC) may assign an optional side quest to aplayer's character, and upon completion, reward the player's characterwith in-game items, experience, upgrades, new powers or abilities, orthe like within the virtual world. Some video games feature“achievements” such as “win 10 games.” Unlike objectives, achievementsare tied to a player's account, not to events in a particular singleplayer storyline. In embodiments disclosed herein, multiple playerscannot join and play or interact in an instance of a single playerstoryline at the same time (though many players may be playing separateinstances of their own single player storylines on different devices atthe same time).

Multiplayer game modes allow two or more players to play together,providing a social aspect that can make video games more enjoyable. Forexample, players can compete against each other in game modes such asteam battles, king of the hill, capture the flag, escort/eliminate acharacter, racing, battle royale, attack/defend a target, and the like.Players can also play cooperatively, such as in a cooperativemultiplayer mission, in a player versus environment mode, team survivalmode, and the like. Multiplayer game modes typically have one or moremultiplayer objectives, and some multiplayer game modes can feature aseries of multiplayer objectives in a quest format. The multiplayerobjective can be based on a competitive or cooperative interaction withother players. For example, the cooperative multiplayer mission may havea series of multiplayer objectives different from the single playerstoryline, such as to first reach a destination together, defeat theenemies there, retrieve an item, and escape to safety. In someembodiments, the multiplayer objective can also be unaffected by and/ornot affect a progression of the single player storyline. For example,players may be able to participate in a team battle multiplayer gamewhere the multiplayer objective is to defeat the other player teams,regardless of the storyline progress of individual players. Similarly,in some embodiments, winning or losing the multiplayer team battle maynot have any impact on the single player storylines of participants.

The multiplayer games take place within an instance of a multiplayermap. In some embodiments, a multiplayer map includes at least a spatiallayout of an area in a virtual world in which characters and/or objectscontrolled by multiple players can interact with each other and/or withNPCs or other objects in the virtual world. Maps can include twodimensional layouts (for example, in side-scrolling games), threedimensional layouts (for example, in first person shooters), perspectivelayouts, layouts of battle arenas, and the like. In-game characters caninteract with each other within the virtual world if they are in thesame instance of a particular map.

Video games can include a library of maps to support multiplayer play.In some video games, the maps can include layouts that are the same asor similar to layouts from the single player storyline. For example, ifpart of a single player storyline takes place in an area having a castlelayout, then the castle layout can be re-used in a multiplayer map,which can be optionally modified so that characters are restricted toremain inside the castle. Video games can also include maps that aredifferent from the single player environment. Some maps may beassociated with particular multiplayer objectives. For example, a mapfeaturing a hill can support a king of the hill multiplayer competition,whereas an underwater map may not.

As disclosed herein, the multiplayer video game experience can beimproved. Multiplayer maps can be dynamically modified to support thecompletion of one or more single player objectives for a plurality ofplayers. For example, a first objective can be selected from among oneor more storyline objectives associated with a first player's progressin the first player's storyline. A second objective can be selected fromamong one or more storyline objectives associated with a second player'sprogress in the second player's storyline. As will be described herein,when the first player and the second player play the video game inmultiplayer mode, a map may be selected based at least in part on boththe first player's progress and the second player's progress in theirrespective storylines. The map may be selected at least in part forsupporting in-game mechanics enabling completion of the first objectiveand the second objective. The combination of the first objective, thesecond objective, and the map may be selected in part for theircompatibility with each other. Combinations of objectives, such as acombination including the first objective and the second objective, canadditionally or alternatively be selected in order to provide larger orthe largest quantity of players with storyline objectives to completewhile playing on the multiplayer map.

Systems, tools, and methods disclosed herein can help video gamedevelopers improve the coverage of combinations of various objectivesand maps. A directed search can be used to determine restrictedcombinations. A computer system can generate and suggest changes to thevideo game to improve coverage.

Example Multiplayer Game

FIG. 1 illustrates an example of two players selecting to play amultiplayer mode of a video game. FIG. 1 includes a first player (Adam)and a second player (Bob). The first player is playing a fantasy videogame on a first computer system 101 configured to generate a first videooutput 103. The second player is playing the fantasy video game on asecond computer system 105 configured to generate a second video output107. The computer systems 101 and 103 are connected to each other via anetwork 109 such as the Internet or a local area network.

The first computer system 101 and the second computer system 103 can be,for example, a console, a desktop, a laptop, a smartphone, a handheldgaming device, and the like. The first computer system 101 and thesecond computer system 103 are running Example Fantasy Video Game, whichincludes a single player storyline mode and a multiplayer mode.

The user interface 103 indicates that the first player (Adam) hasprogressed in the single player storyline to level 2 and shows Adam thathis friend Bob is also online. The user interface 107 indicates that thesecond player (Bob) has progressed in the single player storyline tolevel 3 and shows Bob that his friend Adam is also online. Adam and Bobcan communicate and coordinate to play a particular multiplayer gamemode of Example Fantasy Video Game together, such as a one versus onemode where the multiplayer objective is to defeat the other player, or abattle royal mode where the multiplayer objective is to be the lastplayer remaining.

In response, and as further illustrated in and described with respect toFIG. 2, a computer system can select a combination of objectives for theplayers to complete in the multiplayer game mode. A first objective canbe selected among one or more first single player storyline objectivesavailable to the first player in the single player storyline mode. Asecond objective can be selected from among one or more second singleplayer storyline objectives available to the second player in the singleplayer storyline mode. A multiplayer objective, such as to defeat theother player's character, can be selected based at least in part on auser request to play a selected game mode (1v1) of the multiplayer game.The computer system can also select a multiplayer map supporting atleast the first objective, the second objective, and the multiplayerobjective based at least in part on their compatibility with each other.

FIG. 2 illustrates an example system for dynamically generating amultiplayer map based on single player storyline objectives. FIG. 2continues the example described with respect to FIG. 1. FIG. 2 includesa table 201 showing storyline objectives associated with levelprogression through a single player storyline, a first user profile 203,a second user profile 205, multiplayer game mode data 207, constraintdata 209, a map library 211, a computer system 213, and a multiplayermap 215. The multiplayer map 215 includes a layout showing the relativelocations of player starting points, a road leading to a house, ghosts217 and snakes 219 as default units, wizards 221 a-221 b, and potions223 a-223 c. In various embodiments, the map 215 can indicate locationsof individual units, locations of groups of units, locations where thoseunits will repeatedly spawn or be created, and the like.

The table 201 shows storyline objectives assigned to players at eachlevel of six levels in the single player storyline mode. For example,the storyline objectives available to a player at level 2 in thestoryline includes both defeating 5 elves and defeating 10 wizards, bothof which are required to be completed in order to progress to level 3 inthe storyline. At level 3, a player's available quests include gathering10 gold or gathering 10 potions, either one of which can be completed toprogress to level 4 in the storyline. Some levels, such as level 6, mayinclude objectives to be completed in a sequence: a player's charactermust first dive into the ocean where eel monsters can be encountered,and then defeat the eel monsters. Other storylines may includenon-linear progression, different storyline endings, different orders ofobjectives, and other variations.

The first user profile 203 provides data about a first player who sent afirst request to play a multiplayer mode of the video game. The firstuser profile 203 indicates a single player storyline progress of thefirst player. The single player storyline progress can be indicateddirectly or indirectly, such as by identifying the presently pendingstoryline objectives for the player or with reference to a level in thesingle player storyline. The level provided in the user profile 203 canbe referenced against the table 201 to determine pending single playerstoryline objective(s) of the first player, which in this exampleincludes defeating 5 elves and defeating 10 wizards.

The second user profile 205 indicates similar data about the secondplayer, including who sent a second request to play the multiplayer modeof the video game and data about the storyline progress of the secondplayer. The storyline progress of the second player can indicate or beused to determine pending single player storyline quest(s) of the secondplayer which, in this example, include gathering 10 gold or gathering 10potions. Subsequent discussions of the first player and the secondplayer will be based on the understanding that the first player and thesecond player have started and progressed to different parts of thesingle player storyline unless explicitly indicated otherwise.

Multiplayer game mode data 207 can optionally indicate a selectedmultiplayer game mode, such as 1v1. The selected multiplayer game modecan be used for selecting a corresponding multiplayer objective such asto defeat the other player.

The map library 211 includes one or more maps that can be played in thevarious multiplayer game modes. In some embodiments, each map in thelibrary can have metadata indicating which storyline objectives orcombinations thereof are compatible with each respective map. In someembodiments, the constraint data 209 includes metadata indicative ofwhich storyline objectives or combinations thereof are compatible witheach respective map.

The constraint data 209 can be used to select one or more maps from themap library 211 according to one or more constraints, as furtherdescribed below with respect to FIG. 3A and FIG. 3B. Certain maps may becompatible or incompatible with certain multiplayer game modes and/orstoryline objectives. A map may be incompatible with an objective if thevideo game code does not support in-game mechanics allowing theobjective to be completed. For example, the map 215 would beincompatible with the level 6 objective to “Defeat Eel Monsters” if thevideo game code does not provide for eel monsters to be present on themap or if the eel monsters were present but could not be defeated. Insome embodiments, a playlist including a plurality of compatiblemultiplayer maps can be selected, and the multiplayer video game can beinstantiated using one of the multiplayer maps from the playlist.

The constraint data 209 can also be used to select a first objectivefrom among the one or more storyline objectives presently available tothe first player and a second objective from among the one or morestoryline objectives presently available to the second player to find acombination of objectives supported by at least one map from the maplibrary 211, where the selected map also supports the multiplayerobjective associated with the selected multiplayer game mode 207. In theillustrated example shown in FIG. 2, the selected first objective is todefeat wizards, and the selected second objective is to collect potions.The Multiplayer Map 1 (Valley) is selected as the multiplayer map basedat least in part on the compatibility of Multiplayer Map 1 with theselected first and second objectives and with the selected 1v1multiplayer objective. In various embodiments, the selected objectivescan be the same as the corresponding single player objectives (e.g.,defeat 10 wizards, gather 10 potions) or a similarly related subset(e.g., defeat 2 wizards, gather 3 potions) that would count as progresstoward the corresponding single player objective.

The computer system 213 can create an instance of Multiplayer Map 1 forthe players to play in and interact with each other as part of theselected multiplayer game mode. The players' characters can spawn at theillustrated starting locations in the map and interact with other unitsin the virtual world (such as the ghosts 217, snakes 219, and wizards221 a-221 b), terrain (such as the road), structures (such as thehouse), and other in-game elements according to the in-game mechanics ofthe video game. The in-game mechanics can also include rules forinteractions, moving, attacking, powering up, gaining experience,gaining lives, losing lives, and the like.

In the instance of the video game in the example of FIG. 2, themultiplayer objective for both players can be to defeat the otherplayer. The players can also be assigned at least one selectedobjective. The first player (and optionally any other players) has thefirst objective to defeat wizards. The second player (and optionally anyother players) has the second objective to collect potions.

The single player storyline progression of the first and second playerscan be affected by their respective completion of the assignedobjectives while playing in the multiplayer mode. For example, anywizards defeated by the first player in the multiplayer game can becredited as progress in level 2 of the single player storyline of thefirst player. If the first player manages to defeat 10 wizards whileplaying in the multiplayer mode with the second player, then userprofile 203 of the first player can be updated to indicate that thefirst player has completed the “Defeat 10 wizards” objective part oflevel 2. Similarly, any potions collected by the second player in themultiplayer game can be credited as progress in level 3 of the singleplayer storyline of the second player. If the second player manages tocollect 10 potions while playing in the multiplayer game, then thesecond player can progress to level 4 in the single player storyline,and the user profile 205 of the second player can also be updatedaccordingly.

FIG. 3A illustrates an example set of player profiles, single playerobjectives, and constraints. FIG. 3B illustrates a table of examplemultiplayer maps and related metadata. The relationships shown in thetables of FIG. 3A and FIG. 3B can be implemented as data tables and/orany type of data structure or combination thereof, such as objects andproperties, key-value pairs, coded logic, and the like.

FIG. 3A includes a first table 300 and a second table 310. The firsttable 300 identifies players, their corresponding progress in the singleplayer storyline, and storyline objectives presently pending for eachrespective player. The second table 310 identifies the single playerstoryline objectives and corresponding constraints, if any.

The constraints indicate incompatibilities of objectives with otherobjectives and/or maps. One type of constraint is a storylineconstraint. For example, if the Giant Dragon is slain in level 4 of thesingle player storyline and is not later resurrected in the storyline,then the Giant Dragon should remain slain in subsequent parts of thestoryline for consistency. If players A and B want to play a multiplayergame, with player A at single player level 4 (Slay Giant Dragonobjective) and player B at level 5, then it would be incompatible withplayer B's progress in the storyline for the Giant Dragon to be aliveagain.

Another type of constraint is a lore constraint. The video game may havelore imposing certain restrictions in the virtual world. The lore canoptionally be reflected in the storyline or the video game's mechanics.For example, in the Example Fantasy Video Game, the elves are too scaredof Orc Land and therefore do not go to Orc Land. Therefore, in the videogame, the objective to defeat elves can be incompatible with any map setin Orc Land.

Another type of constraint is a map constraint. Certain elements of mapsmay be incompatible with certain objectives. For example, wizards,elves, and giant dragons breathe air and would be incompatible with anymaps that are underwater.

Another type of constraint can be a required presence of certain typesof elements in a map. For example, the objective to defeat wizards mayrequire that wizards already be in a map, that a map has available unitspawn locations where wizards can be added, or that the video game codeotherwise allows wizards to be included in the map, such as by replacinganother unit with wizards. As another example, the objective to gathergold can require that gold already be present in a map, that the map hasavailable item spawn locations where gold can be added, or that the mapcan be otherwise modified to include gold, such as by having gold dropupon defeating certain enemies. As another example, the objective toslay the Giant Dragon can require that the Giant Dragon already bepresent in the map or that the map has area available for a dragon lairwith the Giant Dragon to be added to the map.

There can be other types of constraints. For example, the Giant Dragonmay be limited to maps with large open spaces. A map layout of a mediumsized building, for example, would not be large enough to accommodatethe Giant Dragon.

FIG. 3B illustrates a third table 320 identifying multiplayer maps,related elements, related constraints, and compatibility information.Each map can be identified by a number or name. The various maps canhave core and swappable map elements. Core elements can be central to amultiplayer map's design for any number of reasons. For example, themultiplayer map Ocean may be associated with a multiplayer objective forplayers to find sunken treasure, so the Ocean map is designed to includesunken treasure as a core element. As another example, the map Orc Landis designed to include orc type units in view of the name. As anotherexample, the Castle map may have a multiplayer objective for players torescue a princess and be designed to have a princess in one of thecastle rooms.

Swappable elements can be changed for an instance of a map withoutsubstantially affecting the design of a map. Types of swappable mapelements can include units, items, terrain features, resources, artwork,and the like. For example, the Castle map may have soldiers who areguarding the princess, but the Castle map could alternatively includewizards as guards in place of the soldiers. Accordingly, the swappableelements can be replaced by other elements of similar types. Forexample, units can be replaced with other similar units, items can bereplaced with other similar items, resources can be replaced with othersimilar resources, and the like.

The various maps can have corresponding constraints. The constraints intable 320 can be similar to the constraints described with respect totable 310 of FIG. 3A. In FIG. 3B, the table 320 includes affirmativelyand negatively recited constraints. The affirmative constraintsaffirmatively describe what each respective map does feature or include.The negative constraints describe things that each respective map is notcompatible with or cannot support. For example, the Ocean map is anunderwater map and does not support land-only units. The Orc Land maphas ores and does not support water-only units and, according to thepreviously described lore constraint, does not have elves present.

The table 320 includes a column 321 indicating single player storylinelevels that have at least one storyline objective that can be supportedin an instance of the multiplayer map. For example, the Valley map cansupport at least one storyline objective from each of the levels 1through 5, but not six, of the single player storyline mode.

The table 320 can also include entries indicating compatible storylineobjectives and/or incompatible storyline objectives. For example, theOcean map is indicated as compatible with storyline objectives to defeateels, to find potions or other items, and the like. A map is compatiblewith a storyline objective when the map and the storyline objective donot have any inconsistent constraints. The Ocean map is indicated asincompatible with storyline objectives to defeat elves, defeat wizards,or other storyline objectives relating to land-only units, and the like.A storyline objective can be incompatible with a map for having at leastone inconsistent constraint.

Example Multiplayer Map Layouts

FIG. 4 illustrates an example of two multiplayer map layouts including afirst layout 400 for the Valley map and a second layout 420 for theOcean map. A legend 440 is provided to indicate what various symbols inthe map layouts 400 and 420 represent. The first layout 400 indicates aspatial layout of a valley in a virtual world. The second layout 420indicates a spatial layout in an ocean in the virtual world. The maplayouts 400, 420 and any number of other map layouts can be included ina map library for the video game. The maps may represent the placement(such as by coordinates, relative positions, or in another manner) ofvarious elements in a 2D or 3D virtual space, depending on theembodiment. It will be appreciated that the maps as depicted in FIG. 4are illustrative graphical representations of stored map data. The mapdata itself may refer to each element or object included in the map byreference to an object identifier (e.g., an identifier for a 3D snakeobject or treasure chest object) without actually including within themap file the full object data for the various objects or elementsreferenced therein.

The Valley Map includes terrain features, such as a road leading to ahouse, and the locations of default units on the map, such as snakes andghosts. The Ocean map includes terrain features, such as the water, thebottom of the ocean, and a cave. The Ocean map also includes thelocations of default units on the map, such as sharks and eel monsters,and the location of interactive items, such as the treasure chest.

According to the legend 440, X's indicate optional locations in the mapswhere certain types of units can be spawned or otherwise created and O'sindicate optional locations in the maps where certain types of items canbe spawned or otherwise created. Maps can also include optional spawnlocations for resources, terrain features, other players, and the like.By including optional spawn locations that can support a variety ofin-game elements, the compatibility of maps with various storylineobjectives can be expanded by allowing maps to include elementsassociated with storyline objectives. For example, by default, theValley map may not include wizards or elves, but because wizards andelves are units that can be created at the unit spawn locations, theValley map can support the storyline objectives assigned to a player atlevel 2 of the single player storyline. The illustration in FIG. 4 showsstatic spawn locations, but other types of spawn locations can berandom, vary in response to events that occurred in the single playerstoryline, or be otherwise dynamically generated.

In various maps, some, none, or all of the default units may be coreelements. In various maps, some, none, or all of the map elements may beswappable. By including optional swappable elements, the compatibilityof maps with various storyline objectives can be expanded by allowingmaps to include elements associated with storyline objectives. Forexample, by default, the Valley map may not include a Giant Dragon or adragon lair, but by making the house optionally swappable with a dragonlair including a Giant Dragon inside, the Valley map can support eitherof the storyline objectives assigned to a player at level 4 of thesingle player storyline mode.

Although the map layouts illustrated in FIG. 4 are visually drawn forease of understanding, map layouts can be stored in a library as code orother data structures. Some maps can include randomly or algorithmicallygenerated elements. For example, a video games can have an engineconfigured to dynamically generate a valley map having a randomconfiguration of grasslands and hills at various elevations with unitsat randomly or algorithmically selected locations.

Accordingly, a multiplayer map can be modified from a template,generated, assembled, or otherwise configured to include a first elementand a second element. In some embodiments, the first element may beincluded so that the map mechanics allow for the completion of a firstobjective selected from among one or more storyline objectives availableto a first player. The second element may be included so that the mapmechanics allow for the completion of a second objective selected fromamong one or more storyline objectives available to a second player.Additional elements can be included in the map to support storylineobjectives for any number of other players who will be playing in themultiplayer map. Accordingly, two, any plurality, or all of the playersin the multiplayer map can complete a storyline objective in addition toa multiplayer objective while playing on the multiplayer map.

Example Process

FIG. 5 illustrates a block diagram of an example flowchart fordynamically assigning single player storyline objectives in amultiplayer mode of a video game. The teachings discussed with respectto FIG. 5 can be performed by any combination of a server and one ormore connected computer systems (such as the computer systems 101 and105 described with respect to FIG. 1 and/or the computer system 213described with respect to FIG. 2). Accordingly, where disclosure ofperformance is recited, the corresponding communication such as access,transmission, and/or reception of data can be additionally oralternatively implemented. In various embodiments, any combination ofthe blocks can be performed by a client and/or server.

At block 501, a request for playing in a multiplayer mode of a videogame is received from a first player, such as from a computing deviceoperated by the first player.

At block 503, the single player storyline progress of the first playercan be determined. For example, it can be determined that in the singleplayer storyline, the first player is at a particular level or at aparticular objective in a sequence of objectives.

At block 505, one or more first storyline objectives related to thestoryline progress of the first player are determined. The one or morefirst storyline objectives can be storyline objectives from the singleplayer mode of the video game that are presently available and/orassigned to the first player.

At block 511, a request for playing in a multiplayer mode of a videogame is received from a second player, such as from a computing deviceoperated by the second player. Block 511 may occur before or after block501.

At block 513, the single player storyline progress of the second playercan be determined. For example, it can be determined that in the singleplayer storyline, the second player is at a particular level or at aparticular objective in a sequence of objectives. In the illustratedexample, the first player and the second player have progressed todifferent parts of the storyline.

At block 515, one or more second storyline objectives related to thestoryline progress of the second player are determined. The one or moresecond storyline objectives can be storyline objectives from the singleplayer mode of the video game that are presently available and/orassigned to the second player.

At block 520, a plurality of storyline objectives compatible with amultiplayer map can be determined. The plurality of storyline objectivesincludes a first objective selected from among the one or more firststoryline objectives. The plurality of storyline objectives alsoincludes a second objective selected from among the one or more secondstoryline objectives.

The determination of compatibility can be based at least in part onconstraints associated with the objectives and the maps, such asdescribed with respect to FIG. 3A and FIG. 3B. In some embodiments, alook up table of which combinations of objectives are compatible withwhich maps can be used. In some embodiments, a directed search can beperformed. In other embodiments, other types of algorithms can be usedto determine the compatibility based at least in part on constraints.

In some video games where multiplayer games can include more than twoplayers, blocks 501-520 can be extended to include at least one pendingstoryline objective for each player in the multiplayer game. In caseswhere no combination of storyline objectives are compatible with anymap, the process can optionally proceed based on a plurality ofstoryline objectives supporting the largest quantity of players.

At block 530, the multiplayer map can be instantiated in the multiplayermode and feature a multiplayer objective and support for the pluralityof storyline objectives. The multiplayer map can be configured to enableany in-game mechanics needed for completing the plurality of storylineobjectives. For example, any units, resources, items, terrain features,structures, or other elements can be created, swapped in, generated,algorithmically selected, or otherwise made present on a map asdescribed with respect to FIG. 3A, FIG. 3B, and FIG. 4. In gamemechanics can also include events, rules, and other mechanics. Forexample, if an objective requires casting a particular type of spell todefeat enemies at night, then players can be armed with the particularspell in an instance of the map configured to take place at night, evenif the map does not make the particular spell available by default andis set during the day by default.

Other examples of configuring in-game mechanics to support the storylineobjectives can including adding or modifying cut scenes, dialog, NPC's,other objectives, and the like. For example, a competitive multiplayermission may have a multiplayer objective for players to first reach acastle, then defeat the soldier guards, and then rescue a princessbefore the other players. The multiplayer mission may begin with a cutscene where an NPC asks the players for help because the princess hasbeen kidnapped by soldiers, offering a reward to the first player torescue the princess. The plurality of storyline objectives includes afirst objective selected from among the one or more first storylineobjectives, the first objective being to defeat 10 wizards. Theobjective to “defeat wizard guards,” can be additionally added in orswapped in place of the “defeat solider guards” objective, wizards canbe added in the appropriate locations, and the cut scene can be modifiedto mention that wizards, in addition to or in place of the soldiers,have kidnapped the princess.

In the instance of the multiplayer map, a multiplayer objective can beassigned to the players based on at least one of a selected multiplayermode or the multiplayer map. For example, players can select to play ina player versus player or a team survival mode, and the multiplayerobjective can be set as defeating other players or to ensure that yourteam survives, respectively. In some embodiments, the multiplayer modecan depend on a selected map. For example, a team of players inmultiplayer cooperative mode on a castle map may be assigned themultiplayer objective of having at least one team member rescuing aprincess trapped in the castle, whereas a team of players playing inmultiplayer cooperative in an ocean map may be assigned the multiplayerobjective of having at least one team member retrieve sunken treasure.

In the instance of the multiplayer map, the plurality of storylineobjectives from block 520 can be assigned to the players. Assigning theplurality of storyline objectives can include assigning the firstobjective to the first player and assigning the second objective to thesecond player. The first objective can optionally be assigned to otherplayers, such as the second player. The second objective can optionallybe assigned to other players, such as the first player.

At block 540, the completion of objectives by the various players istracked. In response to the completion of the objectives by the variousplayers, block 540 can proceed to blocks 541, 543, and/or 545.

At block 541, the single player storyline progress of the first playercan be advanced in response to the first player's completion of thefirst objective during the multiplayer mode.

At block 543, the single player storyline progress of the second playercan be advanced based on the second player's completion of the secondobjective during the multiplayer mode. The single player storylines ofany other players can also be advanced based on their respectivecompletion of storyline objectives while playing in the multiplayermode.

At block 545, winners and/or losers of the multiplayer mode can bedetermined based at least in part on whether or not the various playerscompleted the multiplayer objective.

Example Developer Tools

FIG. 6 illustrates an example user interface 600 showing compatibilitiesof multiplayer maps with different combinations of levels and storylineobjectives from a single player storyline mode. The user interface 600can help video game developers identify coverage gaps where no or fewcombinations of storyline objectives are supported by multiplayer maps.The user interface 600 includes an example table for a multiplayer gamesupporting single player objectives for at least four players. A firstcolumn 601 indicates combinations of storyline levels (from 1 to N,where N can be any number) that the four players have progressed to,each level being associated with one or more storyline objectives.

The next column 603 indicates which multiplayer maps are compatible orincompatible. Compatible multiplayer maps are indicated as compatible ifthose multiplayer maps support, by default or through programmedconfigurations, at least one storyline objective available for playersat each of the indicated levels without constraint problems. Otherwise,the multiplayer maps are marked as incompatible.

The next column 605 lists, for each level indicated in 601, the variouscombinations of storyline objectives that are available to players inthe single player storyline.

The next column 607 indicates whether the particular combination ofobjectives from column 605 is compatible with at least one multiplayermap.

The next column 609 indicates which multiplayer maps are compatible withthe particular combination of objectives from column 605. Another column(not illustrated) can additionally or optionally indicate whichmultiplayer maps are incompatible with the particular combination ofobjectives from column 605.

The next column 611 indicates which constraints may be restrictingcompatibility between maps from column 603 and the particularcombination of objectives in column 605.

The data can be visually presented so that large gaps in coverage can bequickly identified. The information can be presented in other visualforms, such as in charts, bar graphs, histograms, webs, and the like.Large areas of incompatible combinations can be highlighted, bolded, orotherwise visually indicated.

For example, it can be easily seen that if any player is at level two inthe storyline while another player is at level one in the storyline,then there is no compatible combination of objectives that is supportedon any map. Accordingly, video game developers can resolve theincompatibility by introducing new objectives in level one or level twoto improve coverage, by creating or modifying a map to support acombination of objectives including at least one objective from levelone and one objective from level two, or by taking other similaractions.

FIG. 7 illustrates a block diagram of an example coverage search process700. The search process 700 can be performed by a computer system suchthat the computer system acts as a tool for identifying coverage gapswhere no or few combinations of storyline objectives are supported bymultiplayer maps and/or identifying the causes for lack of support.

Inputs to the search can include a database of storyline objectives 701and related metadata. The related metadata can include, for example,storyline objective sequence data indicating the sequence of storylineobjectives assigned to players as the single player storylineprogresses. The related metadata can additionally or alternativelyinclude constraints related to the storyline objectives. The relatedmetadata can additionally or alternatively include information aboutelements critical to objective completion, such as whether certainitems, units, locations, resources, structures, terrain features,actions, and the like need to be available to enable potentialcompletion of the objective.

Inputs to the search can also include a database of multiplayer maps 703and related metadata. The related metadata can include, for example,constraints related to each of the maps. The metadata can additionallyor alternatively include the number of players supported on each map.The metadata can additionally or alternatively include the elementspresent in each map by default and the elements that can be optionallyimplemented on each map.

Inputs to the search can also include any other type of constraints 705.The other constraints can include, for example, lore constraints, rulesfor matchmaking, and the like.

The process 700 can search for maps that are incompatible with any, all,or certain combinations of storyline objectives. For example, the searchcan find multiplayer maps that are compatible with zero combinations ofstoryline objectives, that are compatible with at most one combinationof storyline objectives, or any other threshold number of combinationsof objectives. The maps, objectives, constraints, levels, resources,elements, or other aspects of the video game can be modified to improvecoverage of maps with more combinations of storyline objectives.

The process 700 can additionally or alternatively search for restrictedcombinations of storyline objectives that are incompatible with any,all, or certain combinations of maps. For example, the search canidentify combinations of objectives (such as an objective to slay aGiant Dragon combined with an objective to defeat eel monsters) that arecompatible with zero maps, with at most one map, or any other thresholdnumber of maps. The maps, objectives, levels, constraints, resources,elements, or other aspects of the video game can be modified to improvecompatibility of the resulting combinations of storyline objectives withmultiplayer maps.

The process 700 can additionally or alternatively search for restrictedcombinations of player storyline progress (such as when players are atcertain levels in the storyline) incompatible with any, all, or certainmaps. For example, the search can identify combinations of levels (suchas level combination 1-2-4-6) for which no pending storyline objectivescan be respectively selected (e.g., selecting a storyline objective fromlevel 1, a storyline objective from level 2, a storyline objective fromlevel 4, and a storyline objective from level 6) to result in acombination of storyline objectives supported on at least one map, atleast two maps, or any other threshold number of maps. The maps,objectives, levels, constraints, resources, elements, or other aspectsof the video game can be modified to improve compatibility of thecombinations of storyline objectives with multiplayer maps.

The process 700 can additionally or alternatively search for restrictedin-game elements that are critical to completing storyline objectivesthat are incompatible with any, all, some, or certain maps. For example,the search can identify elements that are compatible with at most zeromaps, at most one map, or any other threshold number of maps. Forexample, the search can identify that a particular type of resource thatis required to be gathered in a storyline objective is not compatiblewith any map. The maps, objectives, levels, constraints, resources,elements, or other aspects of the video game can be modified to improvecompatibility of the resulting combinations of storyline objectives withmultiplayer maps.

In addition to providing the search results, the coverage search canindicate reasons for compatibilities and/or incompatibilities. Forexample, the search results can indicate whether and/or how manyincompatibilities are caused by a lore constraint, by a storylineconstraint, by certain critical elements being unsupported by maps, andthe like.

The results from the coverage search 700 can be transmitted for display,such as in a user interface on a display screen. The results can bedisplayed as a list, a table, in a visualization such as a graph orchart (for example, as shown in FIG. 6), and the like. The results canbe ordered to show least compatible objectives, maps, levels, and/orelements. The results from the coverage search 700 can additionally oralternatively be provided as an input in the flowchart shown in FIG. 8.

FIG. 8 illustrates a block diagram of an example flowchart 800 forimproving the compatibility of multiplayer maps with combinations ofstoryline objectives. At block 801, structured video game data can bereceived. The structured video game data can include, for example, alibrary of video game code for a plurality of video games, databases andmetadata related to the plurality of video games, and/or the code forthe video game searched by the search 700.

At block 803, a computer system can generate constraints based on thevideo game data. For example, the computer system can use a machinelearning algorithm, classification algorithm, artificial intelligencesystem, pattern recognition system, or other technique to generateconstraints. The generated constraints can reflect the types ofconstraints present in the plurality of video games.

At blocks 805 and 807, the results from FIG. 7 can be received. Theresults can indicate storyline objectives, maps, elements, or otherresults identified by the coverage search 700. At block 809, a computersystem can propose changes to the video game to improve compatibilitycoverage, the proposed changes being consistent with constraints of theplurality of video games.

For example, a classification system can recognize that other videogames in the plurality of video games have types of objectives, levels,elements, game progression, or other aspects that are not in the presentvideo game, so the classification system can suggest that the missingobjectives, levels, elements, game progression, or other aspects beadded to the present video game if doing so is consistent withconstraints and will improve the compatibility coverage in at least oneaspect. The proposal can include code, such as code generated based onor copied from the plurality of video games. The proposal canadditionally or alternatively include a template, such as an archetypetemplate, for developers to fill in with code.

As an example of a proposed change to improve coverage, a system candetermine that there is presently no map supporting a combination ofstoryline objectives for players at levels X and Y in a single playerstoryline mode of a video game. The computer system may determine, basedon the received structured video game data, that quests to collect itemsor resources, such as gold, can be supported across a wide range of bothsingle player levels and multiplayer maps with few constraints.Accordingly, a template can be suggested for developers to add “Gather #gold or other resource” to either level X or level Y if doing so willenable players at levels X and Y to have at least one storylineobjective supported by at least one multiplayer map when playingmultiplayer mode together.

As another example of a proposed change to improve coverage, a systemcan determine that there is presently no map supporting a combination ofstoryline objectives for players at levels Y and Z in a single playerstoryline mode of a video game. Players on these levels may have pendingstoryline objectives A and B, respectively. The computer system maydetermine, based on the structured video game data that in other videogames, that certain types of multiplayer maps have supported objectivessimilar to A and B. The computer system can suggest adding those certaintypes of multiplayer maps so that the combination of objectives A and Bwill be supported by at least one multiplayer map.

At block 811, the proposed changes can be transmitted for display.Developers can review the proposed changes. At block 813, user inputfurther modifying the proposed changes can be received. For example,developers can edit or modify proposed code. If a template was proposed,then developers can fill in the template with code.

At block 815, the changes can be implemented in a video game to improvethe compatibility coverage such that more combinations of players fromdifferent storyline levels have pending objectives supported by moremaps. At block 817, after the changes are implemented, the video gamecan be played in a multiplayer mode supporting single player storylineobjectives as described with respect to FIG. 5.
